EEOB 2520 EXAM 1
A - ✔️✔️Which is a correct statement about how the three main categories of
extracellular messengers could be regrouped?
A. Paracrine and neurotransmitter could be combined because they travel only short
distances.
B. Endocrine and paracrine could be combined because fewer types of cells can
release them.
C. Both statements are correct about possible regroupings.
D. Neither statement is correct about possible regroupings.
Homeostatic Control System - ✔️✔️Set of interconnected components that are working
together to keep this parameter where it is supposed to be
Acclimatization - ✔️✔️the process in which an individual organism adjusts to a gradual
change in its environment allowing it to maintain performance across a range of
environmental conditions
Physiology - ✔️✔️How an organism works
Anatomy, Biology, Chemistry, Physics - ✔️✔️Physiology is an integration of
ATP <--> ADP + Pi + energy - ✔️✔️Equation 1
Glucose + O2 + ADP + Pi -> ATP + CO2 + H2O + heat - ✔️✔️Equation 2
CO2 + H2O = HCO3- + H+ - ✔️✔️Equation 3
Equation 3 - ✔️✔️Aiding transport of a key gas, but creating a pH issue
Equation 3 - ✔️✔️Not as common of an equation but is still critical because it gives us
an alternate way to make CO2 that doesn't like to move in our blood
PV=nRT - ✔️✔️Equation 4
Equation 4 (PV=nRT) - ✔️✔️Key equation for lungs, blood pressure
Homeostasis - ✔️✔️Relatively stable maintenance of a body parameter
Dynamic Constancy - ✔️✔️Movement to change homeostasis to
Keep parameter at set point - ✔️✔️Purpose of the homeostatic control system
, Steady state - ✔️✔️Parameter at set point
Steady state - ✔️✔️Asks the questions: Have we achieved this goal? Are we at our
target?
Steady state - ✔️✔️If we are within the range of the set point we are in _____
not changing, energy - ✔️✔️In steady state, system is ____, but ____ is being used
Equilibrium - ✔️✔️_____ is NOT steady state
Feedback - ✔️✔️Reactive disturbance
Negative feedback - ✔️✔️Reaction opposite of disturbance direction
Negative feedback - ✔️✔️More common reaction to maintain homeostasis
Negative feedback - ✔️✔️Return toward SS/SP
Positive feedback - ✔️✔️Reaction continuing in disturbance direction
Positive feedback - ✔️✔️Move further from SS/SP
Feedforward - ✔️✔️Proactive disturbance
Feedforward - ✔️✔️Anticipating a disruption from our steady state and trying to avoid
that disruption
Feedforward - ✔️✔️Limits the degree of feedback required when we do get placed out
of SS
Feedforward - ✔️✔️Less energy is required for this type of reaction
Feedforward - ✔️✔️Biorhythms have a _____ component
Internal clock, environment - ✔️✔️Biorhythms utilize an _____, which is not altered by
the _____
Adaptation, genetic change - ✔️✔️Biorhythms have been developed through _____
and ____ _____
Acclimatization - ✔️✔️How we as individuals adjust our biorhythms
